The is a fixed voltage linear regulator that can output 9V at up to 1A current with an input voltage range of 11 — 35V. The 78xx series of fixed-voltage linear regulators are some of the most popular linear regulators available and have been around for a very long time. They have built-in current limiting and over temperature protection and tend to be fairly robust devices. The prefix may vary depending on the mfr so you may see them listed as LM78xx, MC78xx, L78xx or just 78xx.

Each type employs internal current limiting, thermal shut-down, and safe operating area protection. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed- voltage regulators, these devices can be used with exter- nal components for adjustable voltages and currents.
